This image of Jupiter shows the impact sites of fragments "D" and "G"
from Comet Shoemaker-Levy 9. The large feature was created by the
impact of fragment "G" on July 18, 1994 at 3:28 a.m. EDT. It entered
Jupiter's atmosphere from the south at a 45-degree angle, and the
resulting ejecta appears to have
been thrown back along that direction. The smaller feature to the left
of the fragment "G" impact site was created on July 17, 1994, at 7:45
a.m. EDT by the impact of fragment "D". The "G" impact has concentric
rings around it, with a central dark spot 2,500 kilometers (1,550 miles)
in diameter. This dark spot is surrounded by a thin dark ring
7,500 kilometers (4,661 miles) in diameter. The dark thick outermost
ring's inner edge has a diameter of 12,000 kilometers (7,460 miles) -
about the size of the Earth.
